Which is the "correct server" ?

Are the two identical, and you want to do some sort of load balancing, or are 
they different, in which case what is the answer to the question "which is 
the correct server for packets coming in to this address" ?

No problem here - apply both external addresses to the NIC, have two 
translation rules forwarding packets from ExtAddrA to IntAddrA and ExtAddrB 
to IntAddrB.
